Sinclair mtv1
Got this Sinclair mtv1 and I have perfect sound but no picture all I have is a bright screen and white diagonal lines left to right what may stop the pics from showing as far as maybe a vertical problem or horizontal or maybe something else. I have seen tube tvs do this but don’t know what the problem was. Is it possible bad agc can lose the picture but have good sound.

Hi to all,
Hi Timmy, on the following thread on the UK-VRR forum (post #10) you will find 3 pdf files (photo) pertaining to the repair of the Sinclair MTV Series micro-TVs. Files are too large for this forum. https://www.vintage-radio.net/forum/...d.php?t=206856 The third one is the most complete (39 pages), recent & interesting, updated data Dec 2021. Your TV's failure: do you have a full screen raster or just one bright H line across screen? If only one super-bright line, reduce brightness to avoid damaging the phosphor. If you have a raster, the bright slanted lines are the H retrace, visible because brightness pot is set too high. Can you get a picture? i suppose you're feeding the set from a ATSC to analogue converter + a RF modulator. Hope this helps, Best Regards jhalphen Paris/France Last edited by jhalphen; 03-10-2024 at 06:56 AM. |

NiCads are notorious for puking corrosive effluent into their containment, nickel metal hydride cells seem to do better.
